SPINDLE.

SPECIFICATION forming part of Letters Patent No. 333,914, dated January5,1886.

Application filed April 21, 1884. Serial No. 128,745. (No model.)

T0 all whom it may concern:

Beit known that I, EDWARD E. BRADLEY, of Stonington, county of NewLondon, State of Connecticut, have invented an Improvement in Spindles,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to that class of spindles which is composed oftwo parts, one part having an attached sleeve-whirl, while the otherpart carries the bobbin.

My invention consists, essentially, in aspindle provided with asleeve-whirl and a supporting-case therefor, combined with abobbincarrying spindle having an attached foot secured to thesleeve-whirl loosely, and with an interposed indiarubber or flexiblepacking, as will be described.

Figure 1 represents in elevation the two parts of my improved spindle,the supportingcase, the rail, and parts attached to the spindles beingin section; and Fig. 2 is a like View of a modification.

The spindle A, placed in the bushing ct' in the supporting-case B,secured to the rail C, has attached to it a sleeve-whirl, D. The upperend of the sleeve-whirl is provided with an india-rubber or yieldingpacking, b, and has secured to it by screws d the foot c of thebobbincarrying spindle E, the spindle A thus driving spindle E, thediameter of the screwholes in the foot being greater than the diameterof the screw d, so that the bobbin-carrying spindle may tip or turnsufficiently, as is well understood, topermit it to center itself to itsload. This foot c has a sleeve, c2, which is extended downwardly aboutand to more or less inclose the sleeve of the whirl, and,preferably, asrepresented in Fig. l, the lower end of the sleeve c2 will be providedwith an elongated collar, as at c3, between which and the sleeve of thewhirl is interposed a piece of indiarubber or other yielding packing, h,which affords the spindle E an opportunity to center itself. In someinstances, the packing h being employed, the washer b may be omitted.The interior of the sleeve c2 and the exterior of the upper end of thesleeve of the whirl are of such relative diameter that the interiorsurface of the said sleeve cl and the exterior of the sleeve of thewhirl do not touch when the bobbin-carrying spindle is in true centralposition, the space between the said surfaces to be operative for thepurpose stated requiring to be not more than one one-hundredth of aninch.

In the drawings the space referred to is shown exaggerated; but inpractice it will be understood that the said space is too small to beeasily discernible.

A spindle divided into two parts 'and combined as described andrepresented is undisturbed by the strain or pull of the band, and may berun very steadily. If desired, the sleeve c2 may be shortened, as inFig. 2, and the packing h be omitted.

In another application, No. 128,744, filed concurrently herewith, lhaveshown the sleeve attached to the bobbin-carrying spindle as extendeddcwnwardly about the sleeve of the whirl, and also a exible washer orpacking interposed between the top of the sleeve of the whirl and thefoot ofthe bobbin-carrying spindle of the whirl, but have not thereinclaimed such features, reserving them for this patent.

I am aware that a whirl-spindle has had a projection to enter a notch atthelower end of a bobbin-carrying spindle, as in United States PatentsNos. 255,074 and 288,230.

The supporting-case may be supplied with oil in any usual manner.

I claiml. The supporting-case, spindle A, and its attached sleeve-whirl,combined with the bobbin-carrying spindle having a foot and attachedsleeve, the latter being extended downwardly about the sleeve of thewhirl, and with means to connect the parts to effect the rotation of thebobbin-carrying spindle from the spindle A, substantially as described.

2. The supporting-case, spindle A, and its attached sleeve-whirl, andthe bobbin-carry ing spindle E, and its foot and downwardlyextendedsleeve, combined with the packing h, interposed between the sleeve ofthe spindle E and the sleeve of the whirl, substantially as described.

3. The supporting-case, the spindle A, its attached sleeve-whirl, andthe bobbin-carrying spindle provided with a foot and a sleeve, combinedwith an elastic washer interposed between the lower end of the said footand the top of the sleeve of the whirl, and with means to effect therotation of the bobbin-earrying spindle from the spindle A,substantially as 5 described.

4. The supporting-case, the spindle A, and its attached sleevewhirl, andthe bobbin-carryng spindle E and its attached foot, combned with theelastic washer interposed be- Ic tween the foot of the spindle E and theupper end of the sleeve of the whirl, and with screws Z in holes ofgreater diametei` in the said foot, substantially as described.

In testimony 'whereof have signed my name to this specification in thepresence of two sub- I 5 seribing witnesses.
